Which statement about the origin is correct?

Class 9Coordinate GeometryCoordinate Geometry

AIt lies on both the $x$ -axis and the $y$ -axis.
BIt lies only on the $x$ -axis.
CIt lies only in quadrant I.
DIt lies on the $y$ -axis but not the $x$ -axis.

Step-by-Step Solution

The origin (0, 0) is the meeting point of both axes, so it lies on both the

x

-axis and the

y

-axis.

Answer: A) It lies on both the

x

-axis and the

y

-axis.

Key idea: Plotting a point

To plot

(x, y)

:
1. Start at the origin.
2. Move

x

units along the

x

-axis (right if positive, left if negative).
3. Move

y

units along the

y

-axis (up if positive, down if negative).
4. Mark the point.

Example: (3, −2). From origin, 3 right, 2 down. Lands in quadrant IV.

**Coordinates are ordered**: (3, 2) and (2, 3) are different points.
